Welding is the most common process in the manufacturing industry. No welding can be done without special equipment or machines. Welding machines are required to join two metallic pieces by adding a filler material which is usually the welding rod. These machines make use of different energy sources like friction, electric arc, ultra sound, gas flame, electric beam and laser. Different equipments are used for different processes to get best results. A variety of machines for welding purpose are there is the market and some of them use transformers to convert low current electricity into high current. This machine is comparatively less expensive than others and gives some freedom to the welders to adjust the temperatures accordingly.

Machines for welding are of various types and one such type in the one which use internal combustion engine or electric motor. In such kinds of machines, the power is converted into mechanical energy and then back to electrical energy. Welding machines have become an integral part of the industry and especially the manufacturing industry. In industrial businesses, metal is one of the most important things to be considered because metals which are not shaped or fused properly are invaluable. It is not possible to fuse metal of every type with a typical welding supply; it needs to be changed depending on the metal. Different welding machines are needed for each and every metal.

Every welding machine has its own quality, which is why each machine is important to each metal fusion associated with it. Welding involves a lot of risks, therefore it is important to use specific welding equipment for any particular work. It is essential to create a safe welding environment and for that it is important to check all the Diesel Engine against the safety guidelines. Since welding can be risky, some defensive equipment should also be used like helmet or mask along with the machines. These security gears are essential for those who closely work with machines used to undertake some welding activity. Some welding machines are inverter based and make use of elements like IGBT and store the high voltage energy in the capacitor. Later on this stored energy is transferred into a transformer and from there the needed welding current is generated. These days automated welding machines are also being used and have resulted in improving the efficiency and quality of work.
